SH EET-DELiVERY APPARATUSI SPECIFICATION forming part of Letters Patent No.'269,021, dated December 12, 1882, 1 Application filed Apr-i122, 1882. (No model.)

To all whom it may concern Be it known that I, LUTHER G. UROWELL, a citizen of the United States,.residing in the city of Brooklyn, county of Kings, and State of New York, have invented certain newand useful Improvements in Sheet-Delivery Apparatus, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

The present invention relates to a folding delivery apparatus designed and adapted to operate in connection with a web-perfecting printing-machine, the primary object of the invention being to produce an improved and I5 simple and compact mechanism, which will deliver the printed product in sheets having two parallel transverse folds.

To that end the invention consists principally in certain features, singly and in combination,

The invention also embraces other features by which the same apparatus is capacitated to deliver the printed. product, when desired, in

half-sheets once folded transversely, or in whole sheets associated in pairs and folded twice transversely.

In said drawings, Figure 1 is a side elevation of a web-printing machine, showing in connection therewith a delivery mechanism embodying the present. invention. Fig. 2 is a longitudinal vertical section of the same. Fig. 3 is a plan view of the delivery mechanism. Fig. 4 is a side elevation of the same, the gearing and frame being removed in order to more 5 clearly show the devices for operating the sbeet-holding pins, &c. Fig. 5 is an end elevation, showing the delivery mechanism located at the side of the printing-machine. Fig. 6 is a plan view of the delivery mechanism sectional view of the web-turner. Figs. 8 and 9 are sectional views of the folding and carrying cylinders and folding-rolls, showing the operation of 13116331118 when adjusted to fold 5 and deliver whole sheets. Figs. 10 and 11 are like views, showing the operation of said cylinders and rolls when adj ustedto operate upon half-sheets. Fig. 12 is an end elevation of the delivery apparatus. Fig. 13 is a detail,show- 5o ing the devices for controlling the sheet-hold ing pins. Fig. 14 is a modified form of the same; and Fig. 15 is an end .view of the folding and carrying cylinders, showing a different form of cams for operating the sheet-holding pins. 5 The mechanism for perfecting the web of paper, as shown in the present case, consists of type-cylinders 1 2, and impression-cylinders 3 4, the platesupon the former being inked from the fountains 5 6 through trains of dis- 6o tributing and form rollers 7 8, all of which are mounted in bearings in a suitable frame in substantially the relative positions shown, and are driven in unison in the usual manner.

For convenience in placing, the plates upon 6 the cylinders and in removing the same, a portion of the form-rollers may be mounted in swinging frames, as 9 10', so as to be turned back, as shown by dotted lines in Fig. 1.

The web of paper to be perfectedis led from the roll 11, mounted upon a suitable spindle, located above the impression -cylinders, as shown, or in any other convenient position, and after passing around leading-rolls, as 12 13, is printed upon one side by passing between cylinders 2 4. It passes thence around cylinder 4, upward between it and cylinder 3, and then between the latter and cylinder 1, where it is printed upon its other side, after whichit passes downward around guide-roll let to the delivery mechanism. This delivery mechanism consists principally of two revolving carriers, 15 16, provided with engaging gears l7 18, by which they are caused to revolve in unison, motion being imparted to them from 8 the impression-cylinder 3 through intermediate gearing. The carrier 15 is provided with two sets of sheet-holding pins, 20 21, which are pivoted to arms 22 23, fast to rock-shafts 24 25, journaled upon the interior ot' the carrier, and by the operation of which the pins are moved in and out through perforations in the surface of the carrier. The shafts 24 25 are provided with collars 26 27, (see Figs. tand 13,) having each a recess, intowhich extends 5 a projection upon the disks 28 29, respectively. These disks are mounted to turn upon studs projecting from the ends of the carrier, and are provided with arms 30 .31, which are acted upon by cams and lugs, as hereinafterexpins 21.

plained, to protude and retract the pins at the proper times. The disks 28 29 are provided upon that portion of their peripheries opposite or nearly opposite to the projections just referred to with series of notches 32 33, in which rest at all times small projections upon the ends of springs 34 35. These springs are so adjusted that while they will yield to allow the disks to be turned when the arms 30 31 are acted upon by the cams and lugs, they will yet securely hold the disks, and consequently the pins, in whatever position they are moved to.

The disks 28 29, instead of being provided with notches, as 32 33, may be provided with projecting arms, as 99, (see Fig. 14,) the ends of which arms are provided with notches, in which rest the bowls of spring-pressed arms 100, which latter construction will usually be found preferable.

The carrier 15 is also provided with a rotating folding-blade,36;located at a point nearly opposite the pins 20, and of the ordinary construction, and operated in the usual manner to fold the sheets from the carrier into the bite of the folding-rolls 37 38, said rolls being positively driven from the gear 17 of the carrier in the usual manner.

The carrier 16 is provided with a set of sheetholding pins, 39, which are constructed in the manner already set forth in connection with Justin advance of the pins 39 the carrier 16 is provided with a severing-blade, 40, and at a point opposite to the blade 40 it is provided with asecond severing-blade,41. The blade 40 is shown in the present case as an ordinary tixed blade, while the blade 41 is shown as provided with means for giving to it a reciprocating motion in'the manner shown and described in United States Letters Patent No. 180,966. This, however,is not material. Both blades may be fixed or both may reciprocate. At a point about half-way between the blades 41) and 41 the carrier 16 is provided with a rotating folding-blade, 42, which is also of the common construction, and is operated in the usual manner to fold the sheets from the carrier 16 into the bite of the folding-rolls 43 44,-

1ier,'and is secured to the face of a disk, 52,

which is fast to the shaft of the carrier by bolts 53, passing through slots 54 in the gear, asshown in Figs. 1, 5, and 6. By this construction the carrier 15 can be shifted with relation to the gear 17, so that the cutting-blade 40 can be made to coact with either groove 49 or 51, as may be des red. When the carrier is set so that the blade 40 coacts with groove venient distance from thernachine.

49 the blade 41 will, as the carriers revolve, come opposite to the recess in which the folding-blade 36 rests, and will consequently be inoperative; but when the carrier is set so that the blade 40 coacts with groove 51 the groove 50 will be brought into position to coact with blade 41, so that both blades will be operative.

The purpose of this arrangement will be hereinat'ter explained.

A series of tapes, 45, pass around roll 37, between it and roll 38, under feed-roll 48, which is positively driven from gear 17 of carrier 15, and after passing beneath carrier 16 and around roll 43 return beneath an adjustable tensionroll, 47. Lying above and coacting with these tapes, to form a pathway for the sheets between the roll 38 and the carrier 16, are the fixed guides 46, of the usual form. As the folded sheets emerge from the rolls 43 44 they will be deflected by guides 55, so as to follow the surface of roll 43, and will pass between it and feed-roll 56,'which is geared to and positively driven by roll 43, after which they will pass downward along guides 57. Situated a suitable distance below the roll 43, and so positioned that its arms will project between guides 57, is the rotary fly or packer 58, which is composed of a series of S-shaped arms, mounted upon the shaft 59, which is rotated by gears 60 61, so as to make one-half a revolution to each revolution of the carriers.

Just below the fly or packer there is located a series of horizontally-moving tapes, 62, upon which the folded sheets are deposited by the fly, and by which they are carried to any convThese tapes pass around pulleys or a roll, 63, and another roll or series of pulleys, (not shown,) and may be moved continuously or intermittently by connection with any convenient part of the printing or delivery mechanism. One convenientdevice for giving these tapes an intermittent movement is-shown in Fig. 4, in which the fly-sha-ftis shown as provided with a small crank, 64, the pin of which works in the slotted end of a lever, 65, which is pivoted upon the shaft of pulleys 63, so that as the flyshaft revolves the lever will receive a vibratory movement. The lever 65 is provided with one or more pawls, 66, which engage with the teeth of a ratchet-wheel, 67, fast upon the shaft of pulleys 63, and by means of which the vibrations of lever 65 impart an intermittent movement to the pulleys and tapes.

The delivery apparatus just described, although especially adapted to operate in connection with a printing mechanism constructed and arranged as that herein shown, is yet, as will readily be understood, capable of operating successfully in connection with any form of rotary web-printing mechanism. This delivery apparatus may be placed beneath or at one end of the printing apparatus, so that the carriers will lie parallel with the printing'cylso that the carriers will be at right-angles to the printing-cylinders, as shown in Figs. 5 and 6. When in the latter position, which in many respects is to be preferred, it will be found most convenient to drive the carriers through gearl7 instead of gear 13. This may be done, as shown in Figs. 5 and 6, by providing said gear with a set of bevel-teeth, 70, which will.

engage with a similar set, 71, upon an intermediate, 72, which is Connected by a second intermediate, 73, with the gear 74 upon the shaft of cylinder 3. In this latter case, also, the web after passing roll 14 will pass around a turner, by which it will be turned so as to be led at right angles to its previous path of travel.

The primary objectoftheinvention-i. 6., the delivery of the printed product in sheets having two parallel transverse folds, as hereinbefore stated-can be attained by the devicesjust described when the printing-cylinders and the carriers and rolls ofthedeliveryapparatus are of alength only sufficientto operate upon a singlewidth web; but when itis desired that the machine shall be capacitated to associate two sheetsaud deliver them with two parallel transverse folds, the printing-cylintlers and the carriers and rolls of the delivery apparatus will be of a length sufficient to operate upon a double-width web, which, after leaving the impression-cylinder 3, will be split into two single-width webs by an ordinary slitter, 63,

1 located as shown inFigs. 2 and 6. When it is desired to deliver the printed product in fullsized or whole sheets, the carrier 15 will be set so that its groove 49 will be in position to coact with the severing-blade 40, and the web,

if one of double width is used, will be'split by the slitter. When the carriers of the delivery apparatus lie parallel with the printing-cylinders the web, or the two halves of the split web, will pass directly from the roll 14 onto the carrier 15, as shown in Fig. 2. When, however, the carriers are set at rightangles to the printing-cylinders, the web or webs after leaving the roll 14 will be conducted around a webturuer, so as to be led forward at right angles to its or their previous course of travel. Such a turner may consist simply of a bar or plate set obliquely across the path of the web; but in the presentcase it is shown as composed of two bars, 76, the ends of which meet at the middle of the web, so as to form a continuous turning-surlace, as shown in Fig. 6. The bar 75 is rigidly supported in'any convenient manner, as by the plate 77, extending from the cross-bar 78, which is securely fastened to the frame of the machine. The bar 76 is supported upon the edge of a plate, 79, having screwthreaded ears 80, through which passes the extends just beneath the plate, as shown in Figs. 6 and 7. After passing around the turner the web will pass upward around roll onto carrier 15. As its leading end enters the bite of the carriers 15 16 it. will be impaled upon the pins 20, which will be protruded at that point by the lug 86 upon the carrier 16, (see Fig. 3.) coming into contact with the arm 30 of the disk 28. The pins 20 having been thus protruded will be held in that position by the spring 34, as hereinbefore explained, and will carry the end of the web, or the two ends of the split web, around upon the carrier until the blade 36 arrives in position to fold it or them between rolls 37 38, at which time the arm 30 will come into contact with the fixed cam 87, by which the arm will be moved so as to re tract the pins and release the end or ends of the web. When the pins 20 again arrive at the bite of the carriers 15 16 they willbe again operated upon by the lug 86 and protruded as before, and at thesame time the web will be sev-- The pins 21 and 39 will during this operation remain retracted and idle, there being no lugs upon the carriers in proper position to act upon the arms 31 and 83 -to protrude them. The severing-blade 41 will also remain idle, for the reason hereinbefore explained. The end or ends of the web having been folded between rolls 37 3:5 and severed from the web, as described, will be carried forward by tapes 45 until the fold-line arrives at the bite of the tapes and the carrier 16, at which time the pins 39 will have arrived at the same position, (see Fig. 9,) and will be protruded to impale the sheet or sheets by reason of their operating-arm 88 coming into contact with the fixed cam 89. The sheet or sheets thus impaled loo will pass forward upon the carrier 16 until the folding-blade 42 is operated to fold it or them betweenrolls 43 44, at which time the arm 88 will come into contact with the fixed cam 90 and be moved so as to retract the pins and release the sheet or sheets. (See Fig. 8.) The sheet or sheets, having thus received two parallel transverse folds, will then pass outward: between rolls 43 44 and downward between rolls 43 56 into the curve of the arms of the rotary fly 58, by which the lower edges of the folded sheets will be carried downward and backward against the guides 57, while the opposite and advancing ends of the lily-arms will strike the upper edges of the sheets forward and lay them over tlat upon the moving tapes 62. Whenit is desired that the product shall be whole or full-sized sheets,associated in pairs and folded, as just described, the web, after being split, will have its halves associated by laying one beneath the other before they are cut into sheets.

When the delivery apparatus is located as in Figs. 1 and 2, the halves of the split web may be associated by the use ofa turner, 69, of the form shown in United States Patent No. 181,250, as shown in Fig. 2, or by a turner con- IIO shown in full lines in Fig. 6.

sisting of two parallel bars arranged obliquely across the path of the part of the web to be turned or transferred laterally. In this case one of the parts of the split web will pass around roll 14 and directly onto carrier 15, while the other will pass around roll 91 and then aroundthe turner 69, by which it will be transferred laterally, and then onto the carrier 15 beneath the other part of the original web. The turner 69 will be adjustable, so that its position can be varied to secure the proper registration of the impressions upon the associated webs. As in using a turner of the construction shown the web in passing around it will be turned over, the plates must be arranged accordingly upon the cylinder.

When the delivery apparatus is located as in Figs. 5 and 6, the halves of the split web will be associated by adjusting the bar and plate 76 79 to the position shown in dotted lines in Fig. 6, and then leading one half the web around bar 75 and the other half around bar '76, by which, as will be readily seen, both halves will be turned at right angles to their previous path of travel and will at the same time be placed one beneath the other. The two halves thus associated will be led beheath guide-roll 85, the lower end passing directly onto t-he carrier 15, and the upper one passing over roll 94onto said carrier. It is to be remarked that rolls 14, 85, and 94 are all adjustable, so as to regulate the distance traveled by the webs passing over them, in order to secure the proper registration of the webs with each other and the cutting mechanism. The associated webs after entering into the bite of the carriers will, of course, be operated upon in the same manner as the single web, as already explained.

hen it is desired to deliver the printed product in half-sheets, as hereinbefore set forth, the carrier 15 will be set so that its groove 51 will coact with severing-blade 40, which will also bring groove into position to coact with blade 41, as shown in Fig. 10, and the bar 76 will be brought to the position The web, after assing around roll 14, will pass onto carrier 15, as showuin Fig. 2, or around the turner and roll onto the carrier 15,'as shown in Fig. 5. When the leading ends of the two portions arrive at the bite of the carriers 15 16 a lug, 95, upon the end of the carrier lti (see Fig. 8) will come into contact with arm 31, by which said arm will be moved so as to protrude pins 21 and cause them to impale the ends of the web so that they will pass around with the carrier 15. When the carrier has made one-half a revolution the web will be severed by the blade 40 coacting with groove 51, and at the same time the freshly-cut ends will be impaled by the pins 39 (which will be protruded by the lug 96 upon the carrier 15 coming into contact with the arm 85) and be carried around upon carrier 16. (See Fig. 10.) Soon after the blade 40 severs the web the folding-blade. 36 will fold the severed sheets between rolls 37 38, at which time the arm 31, coming into contact with the stationary cam 97, will be moved so as to retract the pins and release the leading ends of the sheets. When the carrier 16 has made a half-revolution from the point where the pins 39 were protruded the blade 41, coacting with groove 50, will sever the web, and the pins 21 will be again protruded, as before explained. The sheets folded by blade 36 between rolls 37 38 will be carried onwardby tapes 45, and will arrive at the bite of the tapes and carrier 16 just in the rear of the folding-blade 42, so as to underlie a considerable part of the sheets held by pins 39. (See Fig. 11.) When the blade 42 arrives in proper position it will fold the sheets upon carrier 16 between rolls 43 44, the pins 39 beingat that time retracted by the cam 90, and said sheets and the sheets from the'carrier 15, which underlie them, will together pass between rolls 43 44 and into the curve of the arms of therevolving fly. By this arrangement the fly acts upon two sheets at a time, and itis permitted to revolve at thesame speed when delivering half as when delivering whole sheets.

- When the delivery apparatus is set to operate upon half-sheets the pins 20 will remain retracted and idle, there being no lug. upon carrier 16 in proper position to act uponarm 30 to protrude them. I

A set of horizontal tapes, 98, may he arranged, as shown in Figs. 5 and 6, to aid in conducting the web around the turner in threading the machine. 7

In Fig. 15 the sheet-holding pins upon the folding and carrying cylinders 15 16 are controlled by devices of a different construction from those already described. In this case the rock-shafts by which the pins are operated are provided with cross-heads, as 117 126 127, each of which is provided at one of its ends with a rod,'as 118 122 128, which slides in bearings formed in cars projecting from the heads of the carrier. These rods are provided with spiral springs, (not shown',) which operate in the usual manner to press the rods outward, so as to normally hold the pins iii a retracted position. The cross-heads at their opposite ends are provided with studs, as 116 124 125, which engage with and travel upon the peripheries of fixed cams 114 119. These cams are 01'' such form and size and so positi'oned that while the studs travel upon their peripheries, as the carriers revolve, they will cause the pins to move in and out; but, for a purpose to be hereinafter explained, they will 'not cause the pins to protrude beyond the surface of the carriers. When, however, loose thim bles, as 115. 123, areplaced upon the studs, the latter will be lorced outward so much that the action of the cams will carry the pins outside the surface of the carriers at the proper points. The cams 114 119 are provided, as shown, with swinging extension-plates 110 121, which may be secured to the faces of the cams or set in recesses formed for the purpose.

These plates are secured to the cams by pivotal screws or studs, so that they may operate .to enlarge the cams when desired, they being against-the opposite face of the cam. When the pins are operated by these devices and it is desired that the product should be delivered in half-sheets once folded, the carriers will be set, as shown in the figure, so that severing-blade 41) will coact with groove 51, and severingblade 41 with groove 50. The extension-plate 110 will be moved outward so as to extend beyond the edge of cam 114, the extensionplate121 will be moved inward so as to be entirely within the edge of cam 119, and thimbles, as 115 123, will be placed upon the studs 116 124. The parts being thus arranged, the pins21, whenthey arrive at the bite of the carriers, will be protruded and impale the leading end of the web, and carry it around on the carrier 15. At the end of a half-revolution the web will be severed by theblade 40, and the freshly-cut ends will be taken by pins 39, which will at the same time be protruded by the action of the extension-plate 110 upon thimble and stud 115 116. Shortly after this the pins 21 will be permitted to withdraw, and the sheet or sheets upon carrier 15 will be folded by blade 36 in the manner already described. Theblade41 willnextcomeinto action to sever the Web, and the operation will be repeated, the sheets being delivered as already set forth. When it is desired that the product shall be whole sheets twice folded transversely the carriers will be set so that blade 40 will coact with groove 49, the thimble 123 will be removed from stnd124 and placed upon stud 125, plate 110 will be moved to the position shown in dotted lines, and plate 121 will be moved outward so as to extend beyond the edges of cam 119. From this change of the thimble it will readily be seen that pins 20,which were before inoperative, will be made operative, and the pins 21, which were before operative, will be made inoperative, while, from the change in the positions of the extension-plates, the pins 20 will be kept longer in their protruded position, which. is required when whole sheets are operated upon, and the pins 39 be permitted to remain retracted until they have passed the bite of the carriers and arrived in position to take the folded, sheets as they advance from between tapes 45 and guides 46. The operation of the delivery apparatus when thus adjusted will, in the folding of whole sheets twice transversely, be the same as already set forth, and consequently needs no further specific description.
